Quick Guide on Quick Release Hooks Using Load Monitoring


A quick release hook (QRH) is used primarily in maritime and industrial settings to secure and release loads or equipment rapidly. These hooks provide fast and efficient connecting and disconnecting lines, cables, or chains without manual manipulation.

You will typically find quick-release hooks used for rapid deployments or emergency releases, such as in docking operations, towing, rigging, mooring, and securing cargo on ships and offshore platforms.

Quick release hooks feature a lever or mechanism that, when activated, disengages the locking mechanism, allowing the hook to open and release its load almost instantly. This can be particularly valuable in emergencies where a rapid release of tension is necessary to prevent accidents or damage.

Additionally, quick release hooks are often designed to be robust and durable, capable of withstanding heavy loads and harsh environmental conditions.

Combining force measurement devices with quick release hooks enhances the safety, efficiency, and control of various applications. Using a load cell in a quick release hook adds a layer of safety and functionality to the hook mechanism. 

Types of Quick Release Hook Mechanisms Using Force Measurement Solutions

Mooring systems: Measuring tension on mooring lines helps prevent breakages and ensures safe docking and release of ships.

Rescue operations: Force measurement on harnesses and lifting equipment ensures safe lifting and rescue operations, preventing overloading and accidents.

Construction and rigging: Measuring tension on cables and lines allows for safe and efficient lifting and rigging operations.

Cargo handling: Measuring force on lifting straps and hooks ensures safe and secure handling of cargo containers and other heavy loads.

Interface Load Pins

Top 5 Reasons to Use Load Monitoring Technology with Quick Release Hooks 



#1 Safety - Load cells, including load monitoring pins, allow for real-time load monitoring on the hook. This ensures that the load does not exceed safe operating limits, helping to prevent overloading and potential accidents.

 #2 Precision - By design, load cells accurately measure the lifted or secured load. This information can ensure that the equipment is used within its intended capacity and makes informed decisions during lifting or towing operations.

#3 Alerts and Alarms - Custom load monitoring pins can be equipped with sensors that trigger alerts or alarms when the load approaches or exceeds predefined thresholds. This enables operators to take immediate action to prevent overloading or unsafe conditions.

 #4 Maintenance - Load cells can also be used for monitoring the health and condition of the quick release hook and associated equipment. By tracking load patterns over time, operators can identify potential issues or wear and tear that may require maintenance or replacement.

 #5 Data Logging - There is great value in combining a load cell with data logging instrumentation, allowing operators to record load data over time for analysis and reporting purposes. This can be valuable for documenting compliance with safety regulations, conducting performance assessments, and identifying trends or patterns in load usage.

Why are Interface load pins selected for quick release hook applications?

Our load pins are designed to meet the customer's installation requirements, whether in a new hook design or retrofitting existing equipment with load monitoring capabilities. The options for size or capacity are not restrictive. They are rugged down-hole strain gage load cells using 17-4PH stainless steel.

Interface provides load pins for use in all environments, including subsea. We provide Ex d and Ex i hazardous area certified versions (ATEX and IECEx) upon request. Safe area (non-hazardous area) versions are available as well. With the ability to design and engineer load pins to exact customer specifications, customers can choose single and dual bridges, cabled, wireless, amplified, and many more options. Interface can supply pins with EN ISO 10204 3.1 or 3.2 material certification, EN ISO 13849-1, and EN ISO 13849-2 safety in machinery certification. 

Integrating a load monitoring pin with a quick release hook enhances safety, precision, and operational efficiency, making it a valuable tool for a wide range of lifting and securing applications. Contact our team to explore your quick release hook or load monitoring applications.
